Mars is not known for being a quiet, still place.
Dust storms, violent weather, and changing seasons mean it’s constantly in motion; in some ways, quite similarly to Earth.
But it wasn’t until more recently that we found out how widespread — and profound — their movements are.
In late 2021, a team of researchers reported in the Journal of Geophysical Research: Planets that they tracked megaripple movement on Mars’ north pole.
“This enhanced activity is likely related to the greater sand fluxes found for neighboring dunes which are driven by summer-time seasonal winds when polar ice is sublimating.”
While there’s much interest in understanding Mars’ past through its static formations, landscapes like megaripples help researchers piece together new information about its present.
“This supports the idea that much of the Martian surface is actively being modified and not just ancient or static.”
